    执行编译出来的./video12 800 800 60 得到的图像。像是按照4:3拉伸得到的图像， 并不是裁剪出来的800 *800的正方形

      在video12.cpp里改成了-d /dev/media0， 出图还是会有拉伸的效果，
      附近上传的是rk3588的dmesg 打印。还有video12.cpp的应用程序。还有就是出图效果png文件，帮忙再分析看看是什么原因

        用你们的python demo v4l2dev_2_opencv_show_grey.py出图也是一样的效果

          @nb 我看你执行这两个程序都有报错的提示。
          猜测可能你的板子跟我们例程的板子有所不同。具体而言就是是不是/dev/video0和/dev/media0对应着这个相机？
          看现象就是ROI没有正确按照你想要的配置进去。你可以用i2c脚本直接读取参数的形式来确认这一点。

          ./mv_mipi_i2c.sh -r -f roi -b your_i2c_bus_number

            @veye_xumm 系统启动后 ，直接用python3 v4l2dev_2_opencv_show_grey.py --width=1440 --height=1088 --fps=60 这个来出图，不做任何ROI裁剪 ，得到的图像，也是有拉伸效果。 所以我觉得 应该不是 后期通过i2c配置ROI导致的。

              @nb 相机本身并不具备单个方向缩放的能力，你可以尝试参考7.4.3或者7.4.4保存一个图片，然后查看一下。

                    raw8数据可以直接用这个播放器看，不需要转。另外你可以把原始数据文件压缩一下传上来我看看。

                      你好 ，论坛 不支持上传raw文件，我直接把./yavta -c1 -Fy14-${WIDTH}x${HEIGHT}.raw --skip 0 -f Y8 -s ${WIDTH}x${HEIGHT} /dev/video0 用这个命令抓到的文件，上传到自己的有道云笔记上了，然后上面是分享出来的链接。

                        你这个图片有一些莫名其妙的竖条纹，我觉得相机的输出和你的接收现在是不配套的。你执行

                        ./yavta -c1 -Fy14-${WIDTH}x${HEIGHT}.raw --skip 0 -f Y8 -s ${WIDTH}x${HEIGHT} /dev/video0

                        之前设置WIDTH或者HEIGHT等全局变量了吗？

                          配置了的 写了个脚本 ，会先执行 source ./set-wh.sh 然后再echo打印看下 ，配置的有没有成功

                            你的主板应该不是我用的ROC-RK3588S-PC吧？
                            我怀疑是ROI配置没有配下去。
                            你现在用这个命令读出来roi配置试试：

                            ./mv_mipi_i2c.sh -r -f roi -b your_i2c_bus_number

                              这里得到的结果是0x05a0(1440) 0x0440(1088)

                              你之前提供的脚本是2字节读写的，应该不对, 我做了些调整，改正4字节读写了 2.png

                                  @veye_xumm 我有一个怀疑的点。是驱动里日志打印来看这里获取到最大值mvcam: mvcam_probe: max width 1456; max height 1088
                                  后 然后接着就是读取ROI， mvcam: mvcam_getroi:get roi(0,0,1440,1088)

                                  但是我并没有从驱动代码里找到 有设置ROI为14401088的地方，麻烦能告诉一下驱动里设置ROI为14401088的代码在哪里吗， 我想把驱动代码里设置ROI为1440*1088的代码给注释掉试试。

                                          @nb 看起来你的配置没有问题。
                                          有没有可能是硬件的问题？你试过ROC-RK3588S-PC主板上的结果吗？

                                            @veye_xumm 我们这边 没有ROC-RK3588S-PC 这个硬件，
                                            我觉得 可以再往前面排查一步， 就是模组 出图Max width是1536 Height是1088

                                            然后不知道哪里给设置ROI 设置成了1440 和1088 我想知道 这一步是在哪里设置的。 会不会就是这一步设置成1440 *1088的时候 被拉伸了。
